SPECIFICATION forming part of Letters Patent Ho. 301,620, dated July 8, 1884.

Application filed March 14, 1884. (No model.) i

. f0 ctZZ whom it 111,041 c0ncern:'

Be a known that i I, Joan s. MCGUIRE, of Centreville, in the county of Hudson and State of New Jersey, have invented a new and 1111- proved Oil-Gap Faucet, of which the following is a full, clear, andexact description.

' screw-cap, and a valveplate connected with the same- The aperture B in the plate A is can be screwed.

said screw-cap.

The invention also consists in the combination, with the said valve, of a downwardlyprojec-ting knife or prong for cutting out a piece of sheet-tin, which closes the outletopening in the can until the first oil is-drawn.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of my improved oil-cup faucet on the line Fig. 2 is a plan view of the same. Fig. 3 is a plan view of the under side of the same, showing the knife in the act of cutting the plate that closes the outlet-opening of the can. Fig. 4 is a plan View of the valve and. washer plates.- Fig; 5 is a longitudinal sectionaleleva-tion of a modification of the oilcup faucet, and Fig. 6 isa plan View of the under side of the same.

A metal. plate, A, having a central aper-' ture, B, has the'rini of the aperture bent upward, andthe outer rim of the plate'is bent downward, which plate is secured on the top of the oil-can, and over the outlet-opening in closed by a thin sheet of tin, O, soldered on the under side of the plate A. On the upper surface of the plate A a cap, D, is soldered, which is provided with an upwardly-project ing screw-neck, E, on which a screwpap, F, A rod, G, projects downwardly from the middle of the cap F, and on its lower enda valve-plate, J, is secured, the middle part of which is pressed down, so as to form a bead along the rim of the valveplat-e. A fiat washer-ring, K, made of rubber, pasteboard, or other suitable packing material, rests upon the upper surface of the plate A, and surrounds the aperture B. A

spout, H, projects upward at an inclination from the cap D. From the under side of the valve-plate J a pointed and sharp-edged wire or knife, L, projects downward. The cap D is provided with an air-vent, M, and the screw-cap F is provided with a projecting handle-wire, N.

If desired, the knife L and the tin plate 0 can be dispensed with, as shown in Figs. 5 and 6.

The operation is as follows: When the can is filled and has not been tapped, the screwcap F is raised, the opening B being closed by the piece of tin G. If the can is to be tapped, the cap F is screwed down, causing the knife L to pierce the sheet-tin piece O, and by the further turning of the cap F the knife cuts out this piece of sheet-tin. By screwing down the cap F the rim of the valve-plate J is pressed on thewasher-ring K, and the opening Bis again closed. If oil is to be drawn from the can, the screw-cap F is unscrewed, whereby the valve-plate J is raised, permit ting the ,oil to flow through the aperture B and the spoutH, and if the aperture B is to be closed the cap F is screwed down. The cap F cannot be removed entirely from the neck E, as the valve-plate .I strikes against the bottom of the neck E after the cap F has been raised a short distance. The can is closed hermetically by the piece 0 of sheettin until the first quantity of oil is drawn from the can.

Having thus described niy invention, I claim as new and desire to secure by Letters Patent- 1; The combination, with the screw-neck E,

of as pout, the plate A, the washer K, the

screw-cap F, and the valveplate J, connected with the said cap F, substantially as herein shown and described.

2. The combination,with-an apertured plate having a plate secured to its under side below the aperture, and a screw-neck, of a spout, a screw-cap, a valve-plate held to the screw-cap and below it, and a knife or prong projecting downward from the said valve-plate, substanward from the said valve, substantially as heretially as herein shown and described. in shown and described.

3. The combination, with a screw-neck, 0f a spout, the plate A, on which it is held, the JOHN SILVESTER MCGUIRE 5 tin plate 0 on the plate A, the screw-cap F, Witnesses:

the valve-plate J, connected with the same, JOHN J. MARONEY, and of the prong or knife L, projecting down- JAMES H. MARONEY.
